AB  - The impact of additives on wet clutch friction was studied in a pure sliding regime with speeds of 0.01 to 2 m/sec, and contact pressures of ∼ 3 MPa, using a modified MTM. Simple linear carboxylic acids and mixtures were used as model friction modifiers (FM), including: hexanoic, dodecanoic, and stearic acid, to study the effect of chain length and oleic, elaidic, and 12-hydroxy stearic acids to study the effect of some structural changes on the friction. The model friction modifiers ha lower friction and gave a positive gradient μ-V curve. Friction decreased with model FM chain length, as greater lateral side chain interactions existed, which produced more effective friction reducing layer. The friction was also dependent on the structure of the model FM used. Elaidic acid and 12-hydroxy stearic acid had a higher friction coefficient than the saturated stearic acid. This is an abstract of a paper presented at the Proceedings of World Tribology Conference (Kyoto, Japan 9/6-11/2009).
